Magnets Diamagnetics was discovered by Michael Faraday in 1846, but no bomber at the time thought that it could lead to any appreciable effects. William Thomson (Lord Kelvin), referring to levitation as the problem of "Mohamets coffin," had this to say: "It will obably be impossible ever to observe this phenomenon, on account of the disorder of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble." cover strong enough to lift diamagnetic materials became available during the mid-20th century.
In 1939, Werner Braunbeck levitated small beads of graphite in a pear-shaped electromagnet. Graphite has the largest ratio c /r known for diamagnetics (8x10-5 m3/g); today, this hear can be repeated using just a strong permanent magnet, such as one deem of neodymium, iron and boron. Leaving aside superconductors (which are ideal diamagnetics), basic of all levitated by Arkadiev i...If you want to get a in full essay, rescript it on our website:
